FRED A. BRESSMER, OF DECATUR, ILLINOIS.

PLOW.

Specification of Letters Patent.

Patented Nov. 27, 1906.

Application filed August 9, 1906. Serial No. 329,944.

To all whom it may concern:

Be it known that I, FRED A. BRESSMER, a resident of Decatur, in thecounty of Macon and State of Illinois, have invented certain new anduseful'Improvements in Plows, of which the following is a specification.

The object of this invention is to provide a plow in which the share maybe easily and quickly attached to and detached from the moldboard.

The invention is exemplified in the structure hereinafter described, andit is defined in the appended claims.

In the drawings forming part of this specification, Figure 1 is a planof the under side of a plow-bottom constructed in accordance with myinvention. Fig. 2 is a plan of the upper surface of the plow-bottom.Fig. 3 is an elevation of the plow-bottom on the land side thereof,showing the share partly separated from the moldboard. Fig. 4 is a planof the upper surface of the share. Fig. 5 is a plan of the under surfaceof the moldboard. Fig. 6 is a plan of the under surface of the share.Fig. 7 is a detail of the mechanism used to connect the'share with themoldboard, showing a connection 7 partly completed; and Fig. 8 is asection of the same mechanism, showing the connection completed.

The gist of the idea is to secure the share to the moldboard without theuse of bolts and in a manner to permit quick and easy attachment anddetachment.

The share 1 and thelandside part 2'are made in one piece, and themoldboard 3 and landside 4 are made in another piece. Hitch-blocks 5 areformed on the under surface of the share, and bails 7 are pivotallyconjoined to lugs formed on the hitch-blocks 5. Hitch-blocks 6 areformed on the under surface of the moldboard, and lock-levers 8 arepivotally connected with the hitch blocks 6. The lock levers have eyes 9formed on their swinging ends, and hooks 10 are secured to hitch-blocks6 and adapted to engage the eyes of the lock-lever.

The conjoining edges of the share and the moldboard are beveled, asshown in Figs. 7 and 8, and notched or rabbeted, as shown in Fig. 2. Theconj oining ends of parts 2 and 4 of the landside are rabbeted, as shownin Fig. 3, and the hitch-blocks are also rabbeted at their conjoiningends. The rabbets are formed to permit the share to be slid intoposition against the moldboard, and they partake of the nature ofsockets and tenons to hold the parts against lateral displacement.

After the parts are slid together, as shown in Fig. 7, the bails 7 areswung over the locklevers, the lock-levers are swung into lockingpositions, as shown in Fig. 8, and the hooks 10 are swung intoengagement with the eyes of the lock-levers, thus making a secureconnection between the share and the moldboard.

The connection is easily made in a very short time, and when it isdesired to disconnect the share from the moldboard for sharpening orother purpose the disconnection may be as easily and quickly effected bysimply reversing the described operation.

It is obvious that the shape and proportion of the various details maybe modified considerably without departing from the principle of theinvention, and I therefore do not confine myself to the preciseconstruction shown and described.

What I claim as new, and desire to secure by Letters Patent, is

1. In a plow, the combination of a share and a moldboard each havinghitch-blocks formed on its under surface, bails swingably secured to thehitch-blocks of the share, locklevers pivotally secured to thehitch-blocks of the moldboard, eyes in the swinging ends of thelock-levers and hooks connected with the hitch-blocks of the moldboardand adapted to engage the eyes of the lock-levers.

2. In a plow, the combination of a share and a moldboard both havinginterjoining hitch-blocks formed on their under surfaces, and eachbeingnotched or rabbeted to conj oin with the other, bails swingably securedto the hitch-blocks of the share, lock-levers pivotally secured to thehitch-blocks of the moldboard, eyes in the swinging ends of thelocklevers and hooks connected with the hitch blocks of the moldboardand adapted to engage the eyes of the lock-levers.

In testimony whereof I sign my name in the presence of two subscribingwitnesses.

FRED A. BRESSMER.
